IMPROVEMENT IN WATER-BLEVATOR.

Mor-

The Schedule referred to in these Letters Patent and making part: cf thesame.

To all whom 'it may concern.-

Be it known that I, D.-,A. DUNHAM, of Bilatka, in the county of Putnam,and State of Florida, have invented a new and improvedl\Vate1"-11llevator; andI do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specification.

This invention relates to improvements in devices used for raising orinjecting water by a jet ofv steam. Those at present known to thepublic, which are constructed with reference to the same generalprinciple yof operation as mine, are comparatively complicated andexpensive, theV simplest of them consisting in' an arrangement of twopipes, one within the other, with the necessary accessories ofpelforations and couplings, 85e., for connecting and preserving theproper relative position of the parts.

My invention, While effecting the4 same result, and operating in ananalogous manner, consists of a single pipe of any suitable metal, thesame having a transverse incision made in its under side, andthe shell'being bent in at that point, toform a throat or contracted passage, aswill be hereinafter' more fully described.

The drawing represents a sectional elevation of my improved apparatus',

I take any suitable metallic pipe, A, and bend it into the form bestadapted for the place to which it is tobe applied, for receiving andconveying the water, and provide the proper steam-connection at B,beyond the steam-connection, and preferably at the bottom, or

. that part of the pipe which can be placed in the lowest. position.

I make a water-receiving passage, C, bending the shell of the tubeinward at the place where it is cut to form the said passage, so as tocontract the steampas.

sage as at D, while opening the space C for the water.

The improved water-elevator herein described, consisting of a singlepipe or tube, A, provided onits under side with a transverse incision,to allow the shell of the same to be bent inward at that point tn iorm asteam-passage, D, and also a water-passage, G, as and for; the purposespecified. v
